Abstract

A system for receiving and crushing whole lead acid storage batteries, and for classifying the components of crushed batteries into lead oxide, lead metal, plastic case components, and rubber case components and other fragments. Whole batteries are crushed into component particles, and lead oxide from the batteries is placed in liquid suspension. The lead oxide is subsequently removed by three separate settling and classifying tanks. Lead metal is removed by a liquid upflow column separation. A flotation tank and surface skimming arrangement separates plastic case fragments from rubber fragments.
